Our GL2 series indoor high voltage insulating trucks, a popular selection of vacuum circuit breaker parts, are the latest domestic achievement. It is available in many varieties, excellent in performance, and widely applicable to:
a. energy and infrastructure: power plants, 220KV/110KV substations, primary and secondary distribution systems.
b. industrial production: power supply systems for pulp and paper, construction materials (glass, cement, ceramics), steel and metal products, aluminum, petrochemical and other industrial productions.
c. building:power supply system of large-, medium-sized buildings and residential areas.
d. other: petrochemical, transportation, and mining areas
Rated voltage: 36kV (40.5kV)
Rated current: 630A, 1250A,1600A, 2000A, 2500A
The dedicated propulsion mechanism adopted by the vacuum circuit breaker parts integrates all the features to prevent misuse. The high voltage insulating truck also adopts rod drive to preclude misuse caused by rope drive.
The circuit breaker part is of floor mounting type, suitable for ABB’s ZS3.2-40.5 series medium voltage switchgears and TELLHOW-KYN28A series medium voltage switchgears.
Safe and Reliable
The indoor high voltage insulating truck features low maintenance and improved electrical and mechanical interlock to ensure the safety in switchgear maintenance and operation.
Our commercially available withdrawable vacuum circuit breaker parts have passed rigorous routine tests. Parts and their suppliers are required in accordance with the latest domestic supplier quality management system (SQM) to pass periodic assessment to ensure quality consistency. Our designing, manufacturing, mounting, and servicing comply with rules of ISO 9001: 2000 quality management system.
The design of the indoor high voltage insulating truck is based on European environmental standards, in full compliance with requirements of ISO14001 environmental management system. Our waste parts recycling rate reaches 80%.

Quality Control System
In the production process, each of our vacuum circuit breaker parts is manufactured with advanced processing technology and subjected to routine tests. This is to ensure good quality and consistency before delivery, in line with the requirements of ISO 9001:2000 quality management system. The test reports are signed by our quality control department to ensure the traceability.
The following items will go through our rigorous systematic routine tests:
a. 1 min power frequency withstand voltage test on main circuit: between open contacts, phase-to-phase, phase to earth
b. VCB mechanism operating low voltage test
c. dielectric test in auxiliary and control circuit
d. mechanical characteristic test
e. circuit resistance test
f. out-looking check
